    Abstract: The ATSC 3.0 physical layer broadcast standard is extended with new OFDM numerology, L1 signaling and frame structure aligned with 5G. This is done to enable improved broadcast mobility and convergence 5G release 16 as a Non-3GPP access network. The 5G core network and Broadcast core network interwork over defined interfaces to enable convergence layer 3. This enables improvements of broadcast physical layer for physics of broadcast. The 5G unicast physical layer is enhanced for physics of unicast, and then both are converged at layer 3. This is novel and has many benefits compared to the legacy LTE broadcast method (e.g., Evolved Multimedia Broadcast Multicast Services (eMBMS)), which combines both broadcast and unicast into a single shared LTE frame at layer 1. The eMBMS method is then improved for dominate unicast mode in shared L1 frame. The result is the broadcast performance and efficiency in eMBMS are less than optimal.

    Abstract: Disclosed herein are method and apparatus for Advanced Television Systems Committee (ATSC) 3.0 and non-ATSC 3.0 broadcast Direct to Mobile (D2M) co-exist aligned open radio access network (O-RAN). One aspect of this disclosure operates by generating a broadcast frame conforming to a first communications protocol, where the broadcast frame conforming to the first communication protocol includes a slice start (SS) portion. The embodiment further generates a broadcast virtual frame container including the broadcast frame conforming to the first communication protocol and a broadcast frame conforming to a second communication protocol, where the broadcast virtual frame container further includes a virtual frame start (VFS) portion, and transmits the broadcast virtual frame container.

    Abstract: Apparatuses and methods are provided for generating, transmitting, receiving, and decoding one or more band segmented bootstrap signals and one or more corresponding partitioned post bootstrap signals. For example, a transmitter is configured to generate a first set of symbols and a second set of symbols, where the first set of symbols includes information about the second set of symbols. The transmitter is further configured to generate a third set of symbols and a fourth set of symbols, where the third set of symbols includes information about the fourth set of symbols. The transmitter is also configured to generate a data frame including the first, second, third, and fourth set of symbols. A bandwidth of the data frame includes a first segment and a second segment.

    Abstract: A method disclosed includes receiving data from a plurality of data sources in a broadcast core network for transmission over a radio access network (RAN). The method includes assigning radio spectrum resources for transmitting the data over the RAN according to a policy guidance set by a plurality of network operators for sharing the radio spectrum resources and generating a baseband packet corresponding to the data at a distributed unit (DU) in the RAN. The method includes scheduling transmission of the generated baseband packet to a remote unit (RU) over a fronthaul in a radio topology of a plurality of radio topologies according to the policy guidance. The generated baseband packet is compatible for transmission in the plurality of radio technologies.

    Abstract: Some aspects of this disclosure are direct to a system that includes a first scheduler configured to receive an input packet and generate a first packet to be transmitted using a first radio unit (RU). The system further includes a second scheduler configured to receive the first packet from the first scheduler and generate a second packet. The second packet is to be transmitted using a second RU. The system further includes a first fronthaul operated using evolved Common Public Radio Interface (eCPRI) protocol and configured to direct the first packet to the first RU to be transmitted on a first channel having a first frequency. The system further includes a second fronthaul operated using the eCPRI protocol and configured to direct the second packet to the second RU to be transmitted on a second channel having a second frequency different from the first frequency.

    Abstract: An apparatus and a method are provided for generating and transmitting one or more band segmented bootstrap signals. For example, a transmitter may be configured to generate a plurality of sequence numbers and apply cyclic shift to each of the plurality of sequence number. The transmitter is further configured to map each of the shifted sequence numbers to at least one frequency domain subcarrier of a plurality of frequency domain subcarriers, and translate each subcarrier of the plurality of subcarriers to a time domain sequence. Each subcarrier of the plurality of subcarriers may be shifted with respect to other subcarriers of the plurality of subcarriers, thereby aligning each segment of the band segmented bootstrap signals next to each other in the frequency domain.
